There's no need to ever reload the ui as everything is updated in real time. Keep in mind blocks arrive only every three seconds so that's the frequency of updates, but that's still way better than most other chains.
Of course if you have a dodgy internet connection or are connected to a poor api server your mileage may vary.
@svk I am impressed with all your knowledge about bitshares. Thanks for sharing all of these with the steemit community. I first read a post from you from a good amount of months ago about the TREZOR and how you were able to connect STEEM with it. Any progress on that? Can we put steem or bitshares secured with Trezor? I am now following you, and definitely your post and knowledge deserves to be read for many people in the steemit community. Following you now @gold84
Thanks for the reply!
Interesting. There is no visual element, other than a number change to give the user the impression this is happening.
Maybe an update clock icon.. some movement, would give the user the assurance that the interface is talking to the exchange...
The orderbook flashes when something changes there, and the depth chart updates in real time. This is similar to any centralizes exchange, although I suppose the lack of volume in some markets can make it look static.
